Spodoptera exigua is frequently intercepted from various countries throughout the world, although Mexico is the most common origin, accounting for 75% of the total number of interceptions. Larval development time also depends on the species of host plant, which ranges from vegetable crops to common weeds and plants.

FACs in general are likely to have importantfunctions in herbivore nitrogen metabolism [17], and are perhaps assimilated by the plants from herbivore OSs, as described above [5]. Accessed Host plants play an important role in population increases and outbreaks of cosmopolitan polyphagous insect pest, such as Spodoptera exigua (Hübner; Lepidoptera: Noctuidae). Adults and larvae often are found together in forests and fields; however, adults are not limited to their immediate surroundings, due to their ability to fly. February 11, 2013 "Insect and related pests of flowers and foliage plants (AG-136)" (On-line). During pupation, a larva drops to the ground and digs an underground chamber 1 to 2 cm deep and weaves a silk cocoon. Adult females accordingly exhibit a preference of laying eggs on specific host plants. Classification, To cite this page: living in the Nearctic biogeographic province, the northern part of the New World. 1995. Background The beet armyworm, Spodoptera exigua (Hübner), is a worldwide, polyphagous agricultural pest feeding on vegetable, field, and flower crops. Host-Plant Resistance Breeding programs for resistance to Spodoptera spp. Larval survival was highest on pigweed (94.4%) and lowest on cabbage (67.1%). After laying their last egg clusters, adult females live for just a few more days. results agree with the earlier observation that maize was the minimal preferrd one.

(Luo, et al., 2003), When Spodoptera exigua reaches adulthood, it reproduces in the spring and summer until its death. (Showler, 2001; Wakamura and Takai, 1990; Yong, 2008). As armyworm larvae mature, they exhibit less gregarious behavior. Maize farmers in sub-Saharan Africa recently experienced unusual damage in their farms, attributed to the fall armyworm (FAW) Spodoptera frugiperda (J. E. Smith).

The larvae also feed on nearby plants. Spodoptera exiguaHübner is a polyphagous insect pest of frequently cultivated crops (castor, cauliflower, okra and spinach) in cotton agroecosystem of Pakistan. Annals of the Entomological Society of America, 94/4: 566-575. Abiotic determinants of overwintering success (e.g., temperature, moisture and water balance) have been well studied (Denlinger & Lee 2010). 2003. Yong, E. 2008.
